Wartsila received these orders during the last two quarters of 2021, with the deliveries to be made starting this year.
Six of the vessels in the orders are 13,000 twenty-foot equivalent unit (TEU) container ships undergoing construction at the Hudong-Zhonghua Shipbuilding (Group).
The remaining six vessels are 15,000TEU container ships being built at the Jiangnan Shipyard (Group).
The first ship is projected to be launched in the third quarter of 2023.
In October 2020, Wartsila secured an order to provide similar equipment for nine 23,000TEU CMA CGM ships.
The technology firm also bagged orders for five 15,000TEU ships, of which two have been delivered and three are still under construction.
These vessels feature dual-fuel gas engines that will support renewable energies, including biomethane, synthetic methane and e-methane.
Wartsila president and CEO Håkan Agnevall said: “This large repeat order for a broad scope of Wartsila solutions from a valued customer marks the value of quality, reliability and sharp customer focus. It also highlights our wide range of competences across marine technologies. Both CMA CGM and Wartsila have a common strategy in applying LNG solutions to prepare the way towards carbon free shipping.”
The scope of the solutions from Wartsila includes 60 Wartsila 34DF dual-fuel auxiliary engines, Wartsila’s Nacos Platinum integrated control system, propulsion control systems, STC-13 series Sewage Treatment Plants, and Fuel Gas Supply Systems installed with Wartsila’s Operational Performance Improvement and Monitoring (Operim) system.
The Fuel Gas Supply System depends on digital technology to offer real-time data, enabling the solution to run at optimal efficiency during all weather and sea states.
Last month, CMA CGM teamed up with Shell to finish the first bio-LNG bunkering trial at the Rotterdam Short Sea Terminals in the Netherlands.
